    2: 
    3: \textbf{stringresponse} implements a string answer. An internal \textbf{textline}
    4: tag (see \textbf{\ref{textline}}) is necessary for the student's
    5: response to go in. It can check the string for either case or order.
    6: Possible attributes are:
    7: 
    8: \begin{itemize}
    9: \item \textbf{answer}\index{answer}: required. Specifies the correct answer,
   10: either a perl list or scalar.
   11: \item \textbf{type}\index{type}: optional. Specifies how the string is
   12: checked (like the CAPA styles). Possible values are:
   13: 
   14: \begin{itemize}
   15: \item \textbf{cs}\index{cs}: \textbf{c}ase \textbf{s}ensitive, order important.
   16: \item \textbf{ci}\index{ci}: \textbf{c}ase \textbf{i}nsensitive, order
   17: important. 
   18: \item \textbf{mc}\index{mc}: case insensitive, order unimportant. The mnemonic
   19: for this option is {}``\textbf{m}ultiple \textbf{c}hoice'', which
   20: is how it was used in CAPA: To allow the user to specify choices from
   21: a multiple choices problem, as in {}``adce'', meaning parts a, d,
   22: c, and e are true. Order didn't matter in such a problem. In LON-CAPA,
   23: using \textbf{optionresponse} with True and False foils would be preferable,
   24: but this will remain supported for easier CAPA-to-LON-CAPA conversion.
